Extreme Demon Gacha Trade Checker

Before you accept a trade, put both sides in here. It counts the copies you already own, shows how many leaderboard points the trade adds or costs, how hard each side is to pull again, and gives a W, F or L. Trades are final once both players confirm, so check first.

Rules checked · card data synced · sources

Try an example:

You give

+0 pts

    You get

    +0 pts

      Add the cards on each side. Set how many copies you already own.

      Points use the game's leaderboard rules: holo copies count first at 3×, every extra copy is worth 1/2, 1/3, 1/4… The score is card points only: badges and milestones show on your profile but add no points (checked in the game client). Rarity is how many packs it takes on average to pull those exact cards again. Neither is a market price: cards have no real-money value and trades are final once both players confirm.

      Points, rarity and trade value

      Players argue past each other because they measure different things. The checker scores the first two; the third is up to the two of you.

      Each one is a button in the checker above, so you can change the copies you own and watch the verdict move.

      Flamewall for a holo Acheron

      You give your only Flamewall (Mythic #6, 3,400 pts) and get a holo Acheron (Legendary #27, 1,100 × 3 = 3,300 pts). Points: −100, a small loss. Rarity: a holo Acheron takes about 14,915 packs to pull, Flamewall about 2,582. Take it if you collect rare cards; skip it if every point counts.

      W

      Three Legendaries for one Mythic

      You give Flamewall (3,400 pts) and get Nullscapes, Every End, andromeda, none of which you own: 3,700 pts, so +300, and the three take more packs to pull than the one. If you already own one copy of each, they add only 1,850 and the same trade costs you 1,550 points.

      L

      Spare Silentlocked for a new Tartarus

      Your 2nd Silentlocked (Epic, 360 pts) still counts for half: giving it costs 180. A Tartarus you do not own adds its full 120. Net −60, and the Epic is the rarer card (1 in 1,208 packs against 1 in 842). Ask for a Rare plus a sweetener.

      How points move in a trade

      • Giving your only copy costs the card's full points: Common 10–13, Rare 100–130, Legendary 1,000–1,300, Mythic 3,000–3,800. A holo only copy costs 3× that.
      • Giving a dupe costs what that copy was worth: ½ for a 2nd copy, ⅓ for a 3rd. Holo copies are counted first, so giving a holo while you keep a normal one costs more than giving the normal one.
      • Getting a new level adds its full points; getting a level you own adds ½, ⅓ … of it. A new Rare beats a 3rd copy of a Legendary you already have.
      • Rarity is the average packs to pull those exact cards again. A card packs never give (Limited) counts as impossible to replace.

      Not sure what one card is worth to you? The odds calculator shows its exact points, what your next copy adds and how many packs it takes. The full score ladder per rarity is on how to play.

      Trading questions

      How do I know if a trade is fair in Extreme Demon Gacha?

      Cards have no money value, so judge a trade by what it does to your score and by how hard the cards are to get again. Add both sides to the trade checker with the copies you already own. It gives the points you gain or lose and a W, F or L. When points and rarity disagree it shows "?" and tells you which side wins on which scale.

      What do W, F and L mean?

      W (win): you gain on points and on rarity, or gain on one and break even on the other. F (fair): about even on both. L (loss): you lose on both, or lose on one and break even on the other. "?" means the two scales disagree, so the answer depends on whether you play for the leaderboard or for rare cards.

      Why does giving away a dupe cost me points?

      Every copy counts, just less each time: the 2nd copy of a level is worth ½ of its points, the 3rd ⅓. Giving away your 2nd Silentlocked (360 points) costs 180. Giving away your only copy costs the full value, so check how many you own before you trade.

      Is a holo Legendary worth more than a Mythic?

      On points it is close: a first holo Legendary is worth 3× its 1,000–1,300 points (3,000–3,900), against 3,000–3,800 for a first Mythic. On rarity the holo Legendary usually wins: a holo Acheron takes about 14,915 packs, Flamewall about 2,582.

      Can I undo a trade in Extreme Demon Gacha?

      No. Trades are final once both players confirm. Moderators can cancel trades that break the rules, such as scams or feeding cards to an alt account, but a trade you simply regret stays done.

      Can I sell or buy Extreme Demon Gacha cards?

      No. The rules say cards have no real-money value and ban selling them or trading them for anything outside the site. One-sided trades to feed another account are banned too; small, occasional gifts are fine.

      Do badges count toward my score?

      No. Your leaderboard score is card points only. Badges and milestones show on your profile but add nothing (checked in the game client).
